Can i get help with this problem

Please don't provide handwriting solution

Which of the following compounds has a stereoisomer that is a meso compound? (I) 1,2- dibromocyclohexane, (II) 1,4-dibromocyclohexane, (III) 2,3-dibromobutane, (IV) 2,3-dimethylbutane, (V) 3,4-dimethylhexane. Recall that an achiral species is one that just contains an internal plane of symmetry. However, a meso compound has two or more asymmetric centers and an internal plane of symmetry. I only O l and II I and III I, III, and V O IV only
